Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'delete' implies a destructive operation, the description doesn't specify whether deletion is permanent, requires specific permissions, affects associated resources (e.g., users, nodes), or provides confirmation feedback. This leaves significant behavioral gaps for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
